drm/gem-atomic-helper: Convert simple-kms shadow helpers to create_plane_state

Browse source

drm_gem_simple_kms_reset_shadow_plane() implements the reset_plane
hook for simple-kms shadow-buffered planes. Since the reset hook
conflates initial state creation with hardware and software reset
during suspend/resume, convert it to the create_plane_state pattern.

Replace it with drm_gem_simple_kms_create_shadow_plane_state(), which
implements the create_plane_state hook using
drm_gem_create_shadow_plane_state(). Update
DRM_GEM_SIMPLE_DISPLAY_PIPE_SHADOW_PLANE_FUNCS accordingly.
